Cisco Switches

Cisco end-span, power/data hubs include the Catalyst 3500, 4000 and 6000. The Cisco WS-PWR-PANEL is a mid-span power hub. These hubs each have the capability to power the following Mitel IP Phones: 5001 IP Phone, 5005 IP Phone, 5010 IP Phone, 5020 IP Phone, and 5140 IP Appliance.

The WS-PWR-PANEL is electrically located between a conventional data hub and the powered device. This unit passes through the data pairs from the data hub to the terminal device while inserting power on the spare pairs (4/5 and 7/8).

Before enabling port power this unit generates a signal that a power-ready device will loop back. This signal is transmitted on the 7/8 pair and if this is looped back on the 4/5 pair the hub then assumes a power-ready device is connected and enables power on that port. The hub continuously probes the port with signal to ensure the device is still connected. When the hub no longer detects the looped-back probing signal it assumes the terminal device has been disconnected and disables power to that port.

The Catalyst 3500, 4000 and 6000 series products provide 48VDC on the data pairs (1/2 and 3/6).

Before applying this voltage on its port the Cisco hub first ensures that the attached device is capable of accepting power. It does this by transmitting a Fast Link Pulse (FLP) on one data pair while monitoring the second data pair. A power-ready device will loop back this signal to the hub via the second data pair. Once the hub senses this return signal it ramps up voltage on the port.

Once enabled the port continues to provide power provided the link signal from the terminal device is present. When this signal disappears the port interprets this as a disconnection of the terminal device and then disables power to that port.
